Abstract BACKGROUND Cancer patients experience pathological fractures and the typical poor bone quality frequently complicates stabilization. Methods for overcoming screw failure include utilization of fenestrated screws that permit the injection of bone cement into the vertebral body to augment fixation. OBJECTIVE To evaluate the safety and efficacy of cement augmentation via fenestrated screws. METHODS A retrospective chart review of patients with neoplastic spinal instability who underwent percutaneous instrumented stabilization with cement augmentation using fenestrated pedicle screws. Patient demographic and treatment data and intraoperative and postoperative complications were evaluated by chart review and radiographic evaluation. Prospectively collected patient reported outcomes (PRO) were evaluated at short (2- <6 mo) and long term (6-12 mo). RESULTS Cement augmentation was performed in 216 fenestrated pedicle screws in 53 patients. Three patients required reoperation. One patient had an asymptomatic screw fracture at 6 mo postoperatively that did not require intervention. No cases of lucency around the pedicle screws, rod fractures, or cement extravasation into the spinal canal were observed. Eight cases of asymptomatic, radiographically-detected venous extravasation were found. Systemic complications included a pulmonary cement embolism, a lower extremity deep vein thrombosis, and a postoperative mortality secondary to pulmonary failure from widespread metastatic pulmonary infiltration. Significant improvement in PRO measures was found in short- and long-term analysis. CONCLUSION Cement augmentation of pedicle screws is an effective method to enhance the durability of spinal constructs in the cancer population. Risks include cement extravasation into draining blood vessels, but risk of clinically significant extravasation appears to be exceedingly low.

OBJECTIVE Achieving rigid spinal fixation can be challenging in patients with cancer-related instability, as factors such as osteopenia, radiation, and immunosuppression adversely affect bone quality. Augmenting pedicle screws with cement is a strategy to overcome construct failure. This study aimed to assess the safety and efficacy of cement augmentation with fenestrated pedicle screws in patients undergoing posterior, open thoracolumbar surgery for spinal metastases. METHODS A retrospective review was performed for patients who underwent surgery for cancer-related spine instability from 2016 to 2019 at the Massachusetts General Hospital. Patient demographics, surgical details, radiographic characteristics, patterns of cement extravasation, complications, and prospectively collected Patient-Reported Outcomes Measurement Information System Pain Interference and Pain Intensity scores were analyzed using descriptive statistics. Logistic regression was performed to determine factors associated with cement extravasation. RESULTS Sixty-nine patients underwent open posterior surgery with a total of 502 cement-augmented screws (mean 7.8 screws per construct). The median follow-up period for those who survived past 90 days was 25.3 months (IQR 10.8–34.6 months). Thirteen patients (18.8%) either died within 90 days or were lost to follow-up. Postoperative CT was performed to assess the instrumentation and patterns of cement extravasation. There was no screw loosening, pullout, or failure. The rate of cement extravasation was 28.9% (145/502), most commonly through the segmental veins (77/145, 53.1%). Screws breaching the lateral border of the pedicle but with fenestrations within the vertebral body were associated with a higher risk of leakage through the segmental veins compared with screws without any breach (OR 8.77, 95% CI 2.84–29.79; p < 0.001). Cement extravasation did not cause symptoms except in 1 patient who developed a symptomatic thoracic radiculopathy requiring decompression. There was 1 case of asymptomatic pulmonary cement embolism. Patients experienced significant pain improvement at the 3-month follow-up, with decreases in Pain Interference (mean change 15.8, 95% CI 14.5–17.1; p < 0.001) and Pain Intensity (mean change 28.5, 95% CI 26.7–30.4; p < 0.001). CONCLUSIONS Cement augmentation through fenestrated pedicle screws is a safe and effective option for spine stabilization in the cancer population. The risk of clinically significant adverse events from cement extravasation is very low.

Objective Botulinum toxin (BTX) injections continue to be the mainstay of treatment for laryngeal dystonia (LD). Many patients are entering their 2nd and 3rd decade of treatment. In this study, the dosage consistency of BTX injections over time was examined in patients with long-term BTX use for LD. Methods Retrospective chart review, 1990–2007. Patients with adductor-type LD who had received at least 20 injections to the thyroarytenoid (TA) muscles were included in the study. The change of total dose and patient-reported effective weeks were investigated; data of the first 5 injections were excluded to eliminate initial dose searching. Results 55 patients (11 male, 44 female, mean age 60.6) with a mean follow-up period of 149.9 ± 43.7 months (range 44 to 211 months) were identified. Total number of treatment episodes was 1825 with a mean of 33.18 ± 10.37 (range 20 to 58) and a mean interval of 19.1 ± 1.3 (range 2 to 118) weeks. The average total dose of BTX for each treatment episode was 2.15 ± 0.37 U (range 0.125 to 10.00 U). The total dose trended downward over time; this trend became statistically significant at 13th injection. The overall mean duration of effect was 15.5 ± 1.1 (range 1 to 58) weeks and did not show a significant change over time. Conclusions The BTX dose needed for a constant response in the treatment of LD decreases over time, raising the concern that neural recovery from repeated BTX is not infinite.

Background: Tyrosine kinase inhibitor (TKI) therapy has led to phenomenal improvement in overall survival for patients with CML. Since TKI therapies were introduced and their results observed, very little innovative research has been conducted in CML. However, several important research directions remain, including, evaluating attempts to truly cure CML, i.e., patients off therapy with no detectable disease, evaluating long-term side effects and improving health related quality of life for patients who are unable to discontinue TKIs, and treatment of patients who are resistant to TKIs. Given that CML is a rare disease, this can only be achieved with considerable collaboration amongst CML experts. Such a collaboration is ongoing in the US NIH-funded Life After Stopping TKIs (LAST) study, which directly led to establishing the H. Jean Khoury Cure CML Consortium (HJKC3, named after a founding member, the late H. Jean Khoury, MD). One of the goals of the HJKC3 is to establish a national CML registry. A registry would collect longitudinal patient information to meet the critical need for both early and late outcomes research. A national CML registry is likely the only viable mechanism for identifying this population, enumerating baseline information, and addressing critical questions regarding late outcomes that may otherwise never be answered. This registry would also serve several other goals. The first aim of this registry is to prospectively collect and evaluate patient and physician compliance with recommended monitoring guidelines. The second goal is to collect data on survivorship. Some CML medications are associated with increased cardiovascular risk, nephrotoxicity, and pulmonary complications. Ensuring adequate medical monitoring of these long-term side effects and appropriately intervening is crucial to improve survival in patients with CML. The third goal is collecting patient reported outcome data directly from patients and linking that to compliance, complications, and clinical outcomes data. Lastly, this registry would inform potential clinical trials. Methods: After obtaining IRB approval, a pilot CML registry was developed at our institution with the goal of establishing the architecture for the infrastructure for a national CML registry. During this pilot we had two primary aims: first, to establish the most practical and efficient method for clinical data collection and second, to build and pilot test patient-reported outcome data collection. Retrospective clinical data was collected using REDCap with two primary mechanisms to populate the data into REDCap: 1) direct extraction and transfer of the data from the EHR and 2) manual chart review and data abstraction for complex fields or fields that require clinical interpretation. Broad categories of data that can be extracted from EMR include demographics, prior medical diagnosis, medications, some lab data, and prescription fill history. Examples of those requiring manual chart review include toxicity data, response, and disease progression data. For prospective chart review and patient-reported outcome data collection, informed consent was obtained electronically. Patient-reported outcomes assessments were administered online by emailing the study subjects a link to access a secure REDCap platform hosted by the MCW (CTSI) Clinical and Translational Science Institute. Measures include PROMIS computerized adaptive tests and select additional measures assessing a broad range of physical, emotional, cognitive, and social health domains. Progress: We identified 164 patients with CML to evaluate for inclusion. Of these, 72 (44%) were non-evaluable due to death, not an established patients, or other reasons and were included retrospectively only, while 92 (56%) were identified as potentially eligible for retrospective and prospective data collection. An invitation to join that included consent was sent to the 72 patients who had agreed to be contacted by email. Of those, 50 consented and 45 completed the baseline PROs, representing a 63% response rate. At 6 months, 39 completed the PRO assessment, representing an 87% retention rate. Data regarding human resource utilization are being collected to inform expected overall costs for a national registry. The next step is to expand to other sites in the HJKC3.

Purpose. To describe the minimally invasive technique for cement augmentation of cannulated and fenestrated screws using an injection cannula as well as to report its safety and efficacy.Methods. A total of 157 cannulated and fenestrated pedicle screws had been cement-augmented during minimally invasive posterior screw-rod spondylodesis in 35 patients from January to December 2012. Retrospective evaluation of cement extravasation and screw loosening was carried out in postoperative plain radiographs and thin-sliced triplanar computed tomography scans.Results. Twenty-seven, largely prevertebral cement extravasations were detected in 157 screws (17.2%). None of the cement extravasations was causing a clinical sequela like a new neurological deficit. One screw loosening was noted (0.6%) after a mean follow-up of 12.8 months. We observed no cementation-associated complication like pulmonary embolism or hemodynamic insufficiency.Conclusions. The presented minimally invasive cement augmentation technique using an injection cannula facilitates convenient and safe cement delivery through polyaxial cannulated and fenestrated screws during minimally invasive screw-rod spondylodesis. Nevertheless, the optimal injection technique and design of fenestrated screws have yet to be identified. This trial is registered with German Clinical TrialsDRKS00006726.

Healthy mother and healthy baby are foremost aim of antenatal care. Progressive anatomical and physiological changes during pregnancy are not only confined to the genital organs however within other systems of the body too, some may be felt as discomfort by a pregnant woman. A pregnant woman having pain or burning micturition, fever with chills, nausea, vomiting and cloudy urine having bad smell can be diagnosed as having Urinary Tract Infection (UTI). UTI is most common bacterial infection encountered during Pregnancy and troublesome to the woman suffering from it. Pyelonephritis, premature delivery and other risk such as PROM, IUGR etc. can be the long term result of UTI hence prompt attention is requisite. In the present study Gud-Amalaka Yoga has been tried in 15 patients for evaluation of its clinical efficacy and adverse / side effects if any. It was observed that Gud-Amalaka Yoga showed better results (25% patients were moderately improved, 75% patients were mildly improved). None of the patient reported any adverse effect during or after the treatment.

Abstract Objectives Existing measures of inflammatory bowel disease (IBD) symptoms are not well suited to self-report, inadequate in measurement properties, insufficiently specific, or burdensome for brief or repeated administration. We aimed to develop a patient-reported outcome measure to assess a broader range of IBD symptoms. Methods The IBD Symptoms Inventory (IBDSI) was developed by adapting symptom items from existing clinician-rated or diary-format inventories; after factor analysis, 38 items were retained on 5 subscales: bowel symptoms, abdominal discomfort, fatigue, bowel complications, and systemic complications. Participants completed the IBDSI and other self-report measures during a clinic visit. A nurse administered the Harvey Bradshaw Index (HBI) for Crohn’s disease (CD) or the Powell-Tuck Index (PTI) for ulcerative colitis (UC), and a gastroenterologist completed a global assessment of disease severity (PGA). Results The 267 participants with CD (n = 142) or UC (n = 125), ages 18 to 81 (M = 43.4, SD = 14.6) were 58.1% female, with a mean disease duration of 13.9 (SD = 10.5) years. Confirmatory factor analysis supported the 5 subscales. The total scale and subscales showed good reliability and significant correlations with self-report symptom and IBD quality of life measures, the HBI, PTI, and PGA. Conclusions The IBDSI showed strong measurement properties: a supported factor structure, very good internal consistency, convergent validity, and excellent sensitivity and specificity to clinician-rated active disease. Self-report HBI and PTI items, when extracted from this measure, produced scores comparable to clinician-administered versions. The 38-item IBDSI, or 26-item short form, can be used as a brief survey of common IBD symptoms in clinic or research settings.

(1) Background: To evaluate the efficacy at 6 years postoperative after the implantation of a trifocal intraocular lens (IOL) AT Lisa Tri 839MP. The secondary objective was to evaluate the contrast sensitivity defocus curve (CSDC), light distortion analysis (LDA), and patient reported outcomes (PROs). (2) Methods: Sixty-two subjects participated in phone call interviews to collect data regarding a visual function questionnaire (VF-14), a patient reported spectacle independence questionnaire (PRSIQ), and questions related to satisfaction and decision to be implanted with the same IOL. Thirty-seven of these subjects were consecutively invited to a study visit for measurement of their visual acuity (VA), CSDC, and LDA. (3) Results: The mean monocular distance corrected VA was −0.05, 0.08, and 0.05 logMAR at far and distances of 67 cm and 40 cm, respectively. These VAs were significantly superior to those reported in previous literature (p < 0.05). The total area under the CSDC was 2.29 logCS/m−1 and the light distortion index 18.82%. The mean VF-14 score was 94.73, with 19.4% of subjects requiring spectacles occasionally for near distances, and 88.9% considering the decision of being operated again; (4) Conclusions: Long-term AT LISA Tri 839MP IOL efficacy results were equal or better than those reported 12 months postoperatively in previous studies. The spectacle independence and satisfaction rates were comparable to those reported in short-term studies.

Background:Few patients have been described in the literature with mutations in the Lacasa Domain containing one (LACC1) gene. Its clinical presentation usually associates sustained systemic inflammation associated with chronic polyarticular erosive arthritis. Until now, there have been multiple treatments described to try to control the disease, however, they are generally unsuccessful in the long term.Objectives:Describe the clinical course of a patient as well as the different treatments usedMethods:Clinical chart reviewResults:Female 18-year-old born from a consanguineous Moroccan couple. Mother, brother and sister with similar conditions. She started at 3 years with fever, anemia, intense elevation of acute phase reactants and symmetric polyarthritis (knees, elbows, carps, shoulders, hands and ankles). Subsequent whole exome sequencing identified c.128_129delGT mutation in the LACC1/FAMIN gene. During the course of her illness, she has received treatment with oral, intravenous and infiltrated corticosteroid, methotrexate and etanercept, without getting adequate control of the disease. In 2016, she started treatment with tocilizumab (8 mg / kg every two weeks), obtaining an acceptable control of the disease (requiring periodic infiltrations every 2-3 months due to persistent arthritis). Nonetheless, in April 2019, she consulted for clinical worsening of the arthritis and laboratory test (C reactive protein 99.7 mg / L, erythrosedimentation rate 53 mm / h, leukocytes 13,500/µL and neutrophils 10,930/µL). At that time, she discontinued therapy with tocilizumab and started tofacitinib 5 mg every 12 hours with good evolution. Since its introduction, it has not required joint infiltration again and the inflammatory parameters (persistently elevated previously) have normalized.Conclusion:The jak kinasa inhibitors may be a treatment option in those patients with bad response to conventional therapy.References:[1]Rabionet R, Remesal A, Mensa-Vilaró A, Murías S, Alcobendas R, González-Roca E, Ruiz-Ortiz E, Antón J, Iglesias E, Modesto C, Comas D, Puig A, Drechsel O, Ossowski S, Yagüe J, Merino R, Estivill X, Arostegui JI.

Abstract Patient Priorities Care (PPC) is a model of care that aligns health care recommendations with priorities of older adults with multiple chronic conditions. Social workers (SW), after online training, document PPC in the patient’s electronic health record (EHR). Our goal is to identify free-text notes with PPC language using a natural language processing (NLP) model and to measure PPC adoption and effect on long term services and support (LTSS) use. Free-text notes from the EHR produced by trained SWs passed through a hybrid NLP model that utilized rule-based and statistical machine learning. NLP accuracy was validated against chart review. Patients who received PPC were propensity matched with patients not receiving PPC (control) on age, gender, BMI, Charlson comorbidity index, facility and SW. The change in LTSS utilization 6-month intervals were compared by groups with univariate analysis. Chart review indicated that 491 notes out of 689 had PPC language and the NLP model reached to precision of 0.85, a recall of 0.90, an F1 of 0.87, and an accuracy of 0.91. Within group analysis shows that intervention group used LTSS 1.8 times more in the 6 months after the encounter compared to 6 months prior. Between group analysis shows that intervention group has significant higher number of LTSS utilization (p=0.012). An automated NLP model can be used to reliably measure the adaptation of PPC by SW. PPC seems to encourage use of LTSS that may delay time to long term care placement.

Background:Patients with rheumatic disease are at risk of developing glucocorticoid induced osteoporosis (GIOP) as many are prescribed systemic oral glucocorticoids as an adjunct to their maintenance therapy. Based on the 2017 ACR Guideline for the Prevention and Treatment of Glucocorticoid-Induced Osteoporosis, a good practice recommendation exists that “initial clinical fracture risk assessment should be performed as soon as possible, but at least within six months of the initiation of long term glucocorticoid treatment.1” Long-term glucocorticoid use is defined by duration of 3 months or greater. Fracture risk assessment should include dual energy-ray absorptiometry (DEXA) scan. Patients on greater than or equal to 2.5 mg of prednisone should be treated with an optimal dose of calcium and vitamin D and may benefit from oral bisphosphonate as primary prevention against GIOP if their fracture risk is moderate to high.1Objectives:The aim of this Quality Improvement Project is to assess the current status of provider implementation of GIOP recommendations in the rheumatology clinic. Ultimate goal is to improve osteoporosis prevention in the rheumatology clinic.Methods:We conducted a retrospective chart review of 60 patients in two outpatient rheumatology clinics. Clinic 1 follows patients with lower socioeconomic status and Clinic 2 follows patients with higher socioeconomics. Inclusion criteria were patients on long-term glucocorticoid use, defined as at least 3 months of corticosteroid use of at least 2.5 mg prednisone daily, as well as age less than 65. Females aged 65 or older were omitted to prevent overlap of the United States Preventative Taskforce recommendation for all women ≥ 65 years to be screened for osteoporosis with DEXA scans.2 DEXA scan orders, calcium and vitamin D prescriptions, and osteoporosis medication prescriptions were abstracted. After baseline data obtained, intervention of education of the rheumatology fellows and faculty, and internal medicine residents in the guidelines for GIOP prevention was implemented. In addition, a smartphrase in the electronic medical record was created for provider use when treating patients on chronic corticosteroids. Subsequently, two audit cycles were completed for retrospective chart review.Results:Upon completion of second audit cycle, there was no change in percentage of DEXA scan orders at Clinic 1, however there was a 10% overall improvement in DEXA scan orders in the Clinic 2.In terms of Calcium and Vitamin D prescriptions, there was an overall improvement in both clinics of 19.7% and 13.3% in Clinics 1 and 2 respectfully after the second audit cycle.Additionally, there was a 3.4% increase in osteoporosis medication prescriptions overall subsequent to the second audit cycle in Clinic 1. However in Clinic 2 there was an overall decrease in osteoporosis medication prescriptions of 6.6%.Clinic 1Prior to AuditAudit cycle 1Audit cycle 2Patient percentage without DEXA scan orders30%33.30%30%Patient percentage without Vitamin D/Calcium orders26.40%8.30%6.70%Patient percentage with osteoporosis medication orders23.30%8.30%26.70%Clinic 2Patient percentage without DEXA scan orders50%37.00%40%Patient percentage without Vitamin D/Calcium orders30%26.00%16.70%Patient percentage with osteoporosis medication orders23.30%11.10%16.70%Conclusion:Overall, the results of the intervention were strongest for improvements in Vitamin D and Calcium orders in both clinics.
